Installing the Go Programming Language is pretty easy, but can be a pain when done behind a firewall and there isn’t one page with all the information necessary. So, here is the one page.

For step: “$ sudo easy_install mercurial”

“mercurial” is probably already in your favorite distro, it is for debian at least. So instead of using the easy_install script, try your distro’s package management app. For debian, apt-get install mercurial did the trick. If you insist on doing it manually, you might need a proxy statement in your env like:

You should probably have an .hgrc file with proxy information in it, including the user name and password for the proxy (be sure to take the credentials out again after install, and only put em in when using hg again)

———– .hgrc with just the minimum necessary contents —————-
[http_proxy]
# Used to access web-based Mercurial repositories through a HTTP proxy.

host=myproxy:1234

passwd=mysecretpassword

user=myuser

For step: “$ ./all.bash”

At the moment there are tests ran during the build, requiring network connectivity. There is discussion on the go-nuts mailing list about fixing it, but until then removing “http” and “net” from tests in the make file:

$GOROOT/src/pkg/Makefile

will get you “Go”-ing again.

To do this, search for NOTEST and add entries “http\” and “net\” to the end, using tabs for the indentation. The complete list should look like the following when complete:
NOTEST=\debug/proc\exp/draw\go/ast\go/doc\go/token\hash\image\image/jpeg\malloc\rand\runtime\syscall\testing/iotest\xgb\http\net\

I am often asked how to resize a directory full of images, for free. This is definitely possible and probable there are many ways to do it, but I like to use ImageMagick for this. ImageMagick is available for almost any OS here:

There are so many versions of Bash around and it can be frustrating, to me at least, to do some things for not knowing what is available on a given machine. Well here is one, the for loop. Here are a few different ways to do the same thing (and I am sure there are many others) . The first two below work on current linux machines but only the third works on Solaris 5.8’s version of Bash. Enjoy
